Are the tubes made out of plastic where they screw in? I bought one like this and the plastic stripped. Had to return.

Yes they are and they are. This is not a well made product. I trashed it and went to Petco to by a good one for the cats.

There is a plastic cover at each end, but the pieces screwed together securely. I don't think the inside of the tubes (where the nut insert is) is plastic. But if it is, it's well put together. I had no problems with mine.

No they are plastic. They work really well! Pay attention to how the old ones are threaded and just do the same.

Not really sure on that, but if you have gerbils they will chew the connections inside the tubes apart so they wontnhold any more. Had to move to a glass tank for mine as they destroyed over $100 worth of these critter trail houses and accessories

Yes, the tube inside is made of stainless steel. It is a decent unit, but just mediocre quality for its very high price.

The tubes I got appear to be nylon rather than plastic. They are pretty sturdy. The unit is in storage so I can't measure the base but I can say you will need to mount it on 2 by's or a sheet of plywood for 1 person operation. Best if you can mount it to the table.

It is metal don't believe they are made of copper just a finish. The rest of the clear tube, and internal funnel tube are plastic.

They are made of plastic, just like the original. After instalation, you might have to corect up and down, but you can't correct left or right.

The question isn't as easily answered as I thought it would be. From their appearance to me, I believe the structure of the tubes is metal. They seem heavy enough and they certainly are sturdy. To get a "for sure" answer, you might have to contact Vivitar.

Same problem here I had a knob crack. The knobs on these units are all plastic with no metal socket in the middle. Better quality knobs have a metal (usually brass) socket and a metal set screw. I bought a set of 4 on eBay. Search for KNOB ELECTRONIC INSTRUMENT SENCORE EICO B&K; HICKOK MERCURY TUBE TESTER LOT OF 4. The better knobs are inexpensive so not sure why the box manufacturer doesn't use them.

The bulb is rubber like a heavy tire rubber. The tube is heat resistant plastic. Here is a link as to the construction of heat resistant plastic: http://answers.yahoo.com/question/index?qid=20090407124250AAgJGiP

All of it is made with a lightweight metal...not sure of specific type..ours is a burnished brass look? But, the entire thing is the same metal. Sorry I couldn't be more helpful. We've had ours for about 5 years and have not babied it at all...no sign of rust at screw points or on the tubing

They are plastic. I have had this for a month now with no problems at all. I don't crank down on the fittings when I tighten them however

Yes! They are just plastic. What I did though was twist the smaller tube into the short bottle and it wrapped around inside. Still worked fine.

Tubes are metal, frames that tubes fit into are plastic and the shelves that lay on top of tubes in frames are metal.

If I remember correctly the manual shows attaching the tubing to the wrong fitting. Attach it to the brass fitting instead of the plastic one

They are plastic inserts, and not part of the metal tube. I have the molded Ram mudflaps and I have about an 8th inc clearance on both sides R&L; and the plastic matches the black on the mudflaps. These are better than I expected and look great.

G. Duncan - The tubular portions are metal but any knobs & adjustment levers are plastic. The screws themselves are metal, but are set in molded plastic. It's held up well over the last 2yrs though. Especially for its price.
